Kushina is a ninja from the former Whirlpool country. She is the mother of Naruto, and her lover is Minato Namikaze, the YondaimeHokage. She had long red hair and she is a beautiful woman. Most of Naruto's ninja skills and personality come from his her. When Tsunade and Jiraiya talked about her, they described her as a talkative tomboy whom became more and more beautiful as she grew up, and also had a jutsu-style like Naruto's.
One day after completing his book, Jiraiya one of the legendary Sannin and Minato's teacher, decided to take a visit while Kushina was pregnant. Jiraiya had given them a copy of his his book about an outstanding ninja, the character in the story being named " Naruto," and he sought their opinions.

The story was like Jiraiya's autobiography, so Minato decided to name his son " Naruto" and Kushina approved, and Jiraiya. was flattered and honored and asked if that made him Naruto's godfather and asked if they were sure, and they were very sure; they wanted their son to be just like Jiraiya.
When the Kyubi came and attacked the village the day Naruto was born, and Minato sacrificed himself to seal the demon in Naruto to save the village. What happened to Kushina is unknown, but Naruto was alone.

While Naruto was battling the Kyubi in his mind for control, Naruto was winning but the Kyuubi's hatred was starting to overpower Naruto, until Kushina appeared. Naruto initially believed Kushina to be the Kyuubi's true form, or a trick of some sort, but he realized that she's his mom because she acts like him. She then binds the Kyuubi in chains so that her and Naruto can talk, saying that Minato sealed both a piece of himself and her in Naruto to help as much as they could for Naruto to control the Kyuubi. Naruto was happy that she was pretty and wondered what he would look like with red hair, and then asked her how she and Minato fell in love. Kushina began to tell Naruto about when she first moved to Konoha, she was a little chunky in the face and the boys made fun of her, calling her "Tomato," and she beat them all up for it which earned her a new nickname, "The Bloody Habanero." And when she first saw Minato, she thought he was just a flakey girly-boy and looked down on him. That is until the Cloud village kidnapped her for her special chakra, she pulled out strands of her hair so she could be found, but it was only Minato who noticed it and saved her, that's when she fell in love with him.

Their conversation gave Naruto a new resolve and fter Naruto successfully took control of the Kyuubi, Kushina revealed shocking news, that she was the previous host of the Kyuubi, and she starts to explain everything to Naruto. She was originally from the Whirling Tides village, the Leaf village and the Whirling Tides village had close ties since the Uzumaki clan were related to the Senju clan and it was customary for Senjus and Uzumakis to marry, even the first Hokage`swife was Mito Uzumaki and was the Kyuubi's first host. The Whirling Tides village were famed for their powerful sealing jutsus and the Uzumakis were known for their strong lifeforces and longevity. She was chosen to be the Kyuubi's new host as a little girl when Mito was close to dying. She then revealed that her pregnancy was attempted to be kept secret, and on the night of her birth, she was taken to a secret location guarded by a seal and some Anbu. Madara appeared, dispatched the Anbu and passed through the barrier. He knew that the seal containing the Kyuubi would weaken during labor and attempted to get the Kyuubi. He took baby Naruto and tried to bargain Naruto's life for the Kyuubi, he threw Naruto in the air and was about to stab him but Minato saved him only to realize that Madara placed explosive seals on Naruto's blanket and quickly got Naruto out of the blanket and fled from the hut which blew up, and Kushina was taken by Madara. Minato placed his Flying Thunder God on Kushina but didn't get there before the Kyuubi was released, Kushina however survived because of her strong life force. Minato brought her back to their home with Naruto and went back to stop Madara...
Madara arrived at the edge of the Leaf village and summoned the Kyuubi there and it started going berserk. Minato appeared on the Hokage monument and stopped the Kyuubi's chakra blast, Madara tried to sneak up on him but Minato reacted instantly and tried to stab Madara, but it passed through him and Madara tried to warp Minato away, but he teleported to safety. Madara followed after where he revealed long chains shackled to his wrists and charged at Minato, he went through Minato and wrapped Minato in the chains, but Minato teleported away. Madara and Minato then charged at each other again, this time Minato threw a kunai which went through Madara's face, but just as Madara grabbed Minato to warp him away, Minato teleported to the kunai he threw and slammed Madara from behind with a Rasengan.
Madara survived the Rasengan and leaped away, with his left arm injured. Unknown to him is that Minato placed a Flying Thunder God seal on his body and instantly stabbed him and placed another seal on Madara's body nullifying his control over the Kyuubi. Madara left promising that the Kyuubi will be his again, and that the world will bow to him. Minato raced back to Konoha in time to stall the Kyuubi from using a chakra blast by summoning Gamabunta to attack it, Minato then teleported it away to Kushina's and Naruto's location. Kushina used her chakra chains to bind the Kyuubi and wanted to drag it back into her and die, but Minato remembered Jiraiya's words about a destined child and a revolution, so Minato believed that Naruto would save the world from Madara and used the Reaper Death Seal to place half of the Kyuubi's chakra in Naruto and the other half in himself, and to seal a little bit of himself and Kushina in Naruto so that they could all see each other one day.
After the story, Kushina apologized for not being there for Naruto as he grew and burdening him with the Kyuubi, but Naruto said he's happy that they're his parents and he knows how much they love him. With that, Kushina fades away.

According to Jiraiya, Kushina is veru wacky and sometimes boyish. Her personality is mostly like her son. Actually, some of her characteristics such as the jutsus that she uses were similar to Naruto's. But as she matures, she became level headed, cheerful and optimistic.
